> The registry/configs/some code is based on a private patch by [~prasanth_j].
> The patch refactors tez pool session to use composition instead of implementation inheritance
from TezSessionState, to allow for two implementations of TezSessionState.
> For now it's blocked on getClient API in Tez that will be available after 0.9.3 release;
however I commented out that path to check that refactoring passes tests.
> When 0.9.3 becomes available, we can uncomment and commit.
> In part 2, we may add some tests, and also consider other changes that are required for
external sessions (e.g. KillQuery, where we cannot assume YARN is present).
> We may also consider a WM change that allows for proportional session distribution when
the number of external sessions and the number of admin-specified sessions doesn't match,
or at least some validation to see that the external sessions are available when applying
a RP.
